The word Spam has been around for some time as a noun, a proper noun, the name of a canned meat product made mainly from ham (the name is a shortened form of spiced ham). The name was trademarked in 1937 and became a popular food for soldiers during WWII.
In 1970, the British TV comedy series, "Monty Python", had a skit called "Spam", about a resturant where everything on the menu was Spam with something, including Spam with Spam.
When the annoying, irrelevant, or inappropriate messages sent on the internet to a large number of users began showing up, someone connected them with the menu at the restaurant on "Monty Python". The noun spam as a word for these messages is a common noun, a word for any and all such messages. This use of the noun spam has a corresponding verb to spam meaning to send the same email message indiscriminately to (large numbers of users).
A further noun derived from this context is spammer meaning someone who sends such e-mails.
